Abstract
Improved apparatus for in-situ forming of polymeric materials. During formation, the polymeric materials can be applied to horizontal or inclined surfaces such as roofs. The improved apparatus is automatically controlled and laser guided.
Claims5
In an apparatus for in-situ formation of polymeric materials, an improvement comprising:
- a first laser fixed to said apparatus whereby the beam of said laser senses the position of the leading edge of said material during said formation;
- a first receiver that relays said sensed edge position to a computer algorithm, said algorithm then deriving the speed of said apparatus required for a predetermined rate of said material formation;
- for a main driving motor that powers said apparatus, a means of adjusting the speed of said motor to achieve said derived required apparatus speed;
- a multi-frame construction of said apparatus wherein a top frame is in a plane above and substantially parallel to a bottom frame;
- a reversible, variable-speed drive motor that propels said apparatus in either of two opposed directions on demand;
- and
- wherein the to frame rotates 180 degrees relative to the bottom frame so that said material formation can be accomplished while said apparatus is moving in either of said two opposed directions.
